Minecraft 1.21 demands Java 21+. Download from Eclipse Adoptium (Temurin 21).
java.exe.Outdated NVIDIA/AMD/Intel drivers cause 40% of GLFW errors.
Reboot post-install. Bonus: Enable "Resizable BAR" in BIOS for smoother frames.
Add these to Minecraft Launcher (Installations > Edit > More Options > JVM Arguments):
-Dorg.lwjgl.glfw.libname=glfw.so -Djava.awt.headless=false --add-launcher-arg=-client
For Linux window woes: -Dorg.lwjgl.opengl.libname=/usr/lib/libOpenGL.so.
🖥️ Install libglfw3 via apt/yum, then export export DISPLAY=:0 before launch.
Delete .minecraft folder (backup worlds!), reinstall via Launcher. Pairs perfectly with Fabric/Forge for mods.
| Symptom | Fix Priority | Success Rate |
|---|---|---|
| Black screen on launch | Driver + Java | 95% |
| Crash in fullscreen | JVM Args | 85% |
